Makrolon SL light diffusing polycarbonate sheet delivers over 20 times more impact resistance than standard and impact modified acrylic even at low temperature extremes. Its toughness minimizes breakage during forming and fabrication, and costly damage that can occur during shipping and installation particularly in cold weather. Once in place, sign faces made from tough Makrolon SL sheet project a positive image long term by withstanding high wind loads and impacts that put other sign face materials out of business.
